This colour edition of a heraldic roll of arms (wappenbuch) does not have a time listed, though I suspect it is well out of our focus time. Another website, https://www.facebook.com/pages/Siebmachers-Wappenbuch/144923885518048# , lists it as having a 1605 completion date. There are a lot of pages from this book on the site, as well as a signet ring engraving service.
